What are gamma ray emitting objects on earth?
Gamma rays are extremely high energy electromagnetic radiation. The source of gamma rays is nuclear "change" like radioactive decay. Radioisotopes, which are either the natural or artificial radioactive isotopes of elements, occur in river deltas, granite, some older paints, some older ceramics, nuclear waste, and specifically irradiated materials that have been made radioactive to be applied to medical devices (like 60Co "pencils" used for medical treatment) or industrial imaging or irradiation sterilization equipments.
Is dark lightning real?
Dark lightning, also known as terrestrial gamma-ray flashes, is a phenomenon that occurs during thunderstorms. It is not traditional lightning but rather high-energy bursts of gamma rays. While dark lightning is a real phenomenon, it is not visible to the naked eye and is still being studied by scientists to understand its effects and implications.
Does earth emit higher energy radiation that the sun?
No, the Sun emits higher energy radiation than the Earth. The Sun emits a wide range of energy, including high-energy ultraviolet, X-ray, and gamma-ray radiation, while the Earth's radiation is primarily in the form of infrared and visible light.
How many protons and neutrons in gamma?
Gamma rays are electromagnetic (EM) energy, and they are at the extreme end of the EM spectrum above X-rays. These high energy, high frequency (short wavelength and short period) rays are created by atomic nuclei when atoms change their nuclear structure through radioactive (or nuclear) decay or when changing from a high energy state to a lower one. As gamma rays are produced in nuclear activity of some sort, if might be argued that neutrons and protons in the nucleus of an atom that is undergoing some sort of nuclear change are the ones responsible for gamma rays. The electrons in an atom are in the electron cloud, and they are not involved with the release of gamma rays.
What does our atmosphere do for us?
The atmosphere protects us because if we had no atmosphere the sun heat ( ultraviolet radiation ) would go straight to earth and kill us all. with the atmosphere it captures enough heat and keeps the rest out!
How often do gamma ray bursts explode?
Gamma ray bursts (GRBs) are relatively rare cosmic events. On average, about one GRB is detected each day in the observable universe. However, these events are unpredictable and can vary in frequency.
What would happen to earth if it got hit by a gamma-ray burst?
Earth gets hit every day by gamma-ray bursts - from far, far away. Depending on how near the gamma-ray burst is, it may cause some serious damage.
What is the biggest explosion in the universe?
Long Gamma ray bursts
How do gamma ray bursts form?
When a star goes supernova it releases a bursts of energy (which is also radioactive) that shoot out from the core. Gamma ray bursts have intense radiation and travel so quickly that if one were to hit earth we would get no warning until it hit us and everything would be vaporized. There is a dying star close to earth and right now at any moment it could go supernova and the worst part is its release of energy is aimed right at us. Gamma ray bursts also form when 2 neutron stars collide or when a neutron star collides with a black hole.
What is 1 discovery for the compton gamma ray?
The discovery of Compton scattering is the phenomenon where incoming gamma rays collide with electrons, resulting in a shift in the gamma ray's wavelength. This discovery helped confirm the wave-particle duality of light and demonstrated the particle nature of light.
What are two possible causes of gamma ray bursts?
neutron stars and black holes
Do gamma ray bursts emit light faster than the speed of light?
Gamma ray bursts emitting light! What is meant by this? Any way gamma ray coming out of a radioactive nucleus is also an electromagnetic radiation as light but with very much higher frequency. Gamma ray also travels with the same speed as light does. According to Einstein's theory of relativity, no radiation can travel with a velocity higher than that of light
How would you compare and contrast X-ray bursts and gamma ray bursts?
If we consider the bursts of high energy electromagnetic radiation from stellar or galactic sources, we encounter bursts of X-rays and gamma rays. The two are similar in that both are examples of high energy electromagnetic energy, and both can be generated by certain stars or galaxies. Additionally, both are the result of nuclear reactions in the star or at sites within the galaxy. But with gamma rays, the sources may be fewer than with X-rays, and the gamma rays are higher in energy than the X-rays.
What is gamma ray bursts?
A gamma ray burst results from an extremely energetic implosion/explosion, as in supernovae or hypernovae events, or the less likely possibility of the combination of 2 neutron stars.
Do Gamma ray burst form a black hole?
In an indirect way, yes. Gama rays are the highest-intensity form of electromagnetic energy. They usually indicate a very power energy source. Most black holes are formed by exploding stars called supernovas. These events can be detected as gamma ray bursts.
What has the author Seth Digel written?

What do astronomer's study?
Lisa Kewley studied cosmic rays and gamma-ray bursts.
